Besides DEA Agent Sanchez' blatant disregard for the 4th Amendment, he refers to his supervisor as 'my Captain,' as does Bree. However, federal agencies don't go by police ranks, therefore, his superior would have the title of Supervisory Special Agent, or SSA, in some agencies, called a more informal: Group Supervisor (GS). The next tier would be Assistant Special Agent in Charge, but nowhere in the hierarchy does Captain appear as a title in the DEA.
